Key metricsaround the main power key switch 506 can include start and stop times.The PCB 518 can time stamp each operation such as device on and deviceoff instances and record these metrics for statistical or reportingpurposes. Other statistics could include time duration between device onand device off operations, which indicate duration of usage for thefloor cleaning machine assembly.

The hour meter switch 508 is controlled by the PCB 518 to calculatehours of operation for the floor cleaning machine assembly, in someembodiments.

The brush motor solenoid switch 510 can be controlled by the PCB 518 toselectively control engagement or disengagement of the brush motor 184of the floor cleaning machine assembly. The PCB 518 can track brushmotor usage time by measuring engagement and disengagement of the brushmotor 184. These statistics can be compared against device on and deviceoff periods to determine how long the brush is engaged compared to theoverall time frame of device on periods. By way of example, the PCB 518can measure that the device is in a device on state for two hours, butthe brush motor was only in use for 15 minutes.

The solution solenoid valve switch 512 can be utilized to controldispensing of solution through a solution dispenser. The PCB 518 cantrack solution dispensing events, which can be used to calculate metricsaround solution utilization.

The safety switch 514 can be controlled with the PCB 518, for example,to lift a scrub head from contact with the floor. In some embodiments,when the PCB 518 activates the safety switch 514, the brush motorsolenoid switch 510 can be controlled to disengage the brush motor 184.Other safety related operations can also likewise be accomplished usingthe safety switch 514.

The vacuum motor relay 516 can be utilized by the PCB 518 to controloperation of the vacuum motor 44 of the floor cleaning machine assembly.

The emergency control switch 520 is controlled by the PCB 518 to controloperation of an emergency switch of the floor cleaning machine assembly.A user can stop operation of the floor cleaning machine assembly byactuating the emergency switch. Actuation of the emergency switch issensed by the PCB 518, causing the PCB 518 to selectively stop the brushmotor 184 and the transaxle 182.

In one embodiment, the emergency control switch 520 can be used toselectively disrupt power provided to the speed control board 530. Thatis, the speed control board 530 is configured to control operation ofthe transaxle motor, by way of the transaxle motor interface 532.

A pair of LED interfaces 522 can be used by the PCB 518 to selectivelycontrol operation of LED lights that indicate operational statuses ofthe device 100, such as forward, backward, power on, and so forth.

The speed potentiometer 524 is controlled by the speed control board 530to sense input from a user that can be used to vary the speed of thedevice. For example, the speed potentiometer 524 can receive a speedindication from a user. The speed indication is received by the PCB 518from input into the speed potentiometer 524. This input is thentranslated into rotational speed of the transaxle motor through thetransaxle motor interface 532.

The forward control handle bail switch 526 provides forward movement ofthe floor cleaning machine assembly. In some embodiments, the speedcontrol board 504 utilizes the backward control handle bail switch 528to provide backward movement of the floor cleaning machine assembly.

In response to signals through the forward control handle bail switch526 and/or signals through the backward control handle bail switch 528,the transaxle motor interface 532 can be used by the speed control board530 to selectively control the operation of the transaxle motor. Forexample, the speed control board 530 can selectively control the forwardand/or backward rotation of the transaxle motor.

As with the PCB 518, the speed control board 530 can include one or moreof the components of the computing machine of FIG. 18, such as aprocessor and memory. To be sure, the memory is configured withexecutable instructions that allow the processor to perform any of thefunctional or process related steps described herein.

Additionally, the PCB 518 can be configured to sense and collect theoperational information of the speed control board 530 as the speedcontrol board 530 controls the transaxle motor interface 532. Forexample, the PCB 518 can determine operational speeds for the transaxlemotor, usage times, and so forth.

The PCB 518 can also control the brush motor 184 and vacuum motor 44,through their respective interfaces, such as brush motor interface 534and vacuum motor interface 536. As with other components, the PCB 518can be configured to sense and collect operational details of thesedevices.

In some embodiments, the PCB 518 communicates within an intelligentsystem 600, illustrated in greater detail in FIG. 15. The PCB 518 caninclude any wired or wireless means of communication such as a wirelesscommunications interface. The wireless communications interface canutilize any protocol for network communication including short rangeprotocols such as Bluetooth, near field communications (NFC), infra-red,and so forth. The wireless communications interface can also includeutilize Wi-Fi, a cellular network, or other similar networks using otherprotocols.

FIG. 15 illustrates an example network system of devices. The networkedsystem 600 comprises a plurality of devices 605, 610, and 615, which canall communicatively couple with a management server 620 over a network625.

Each of the plurality of devices 605-615 can be collocated in the samefacility, such as a building, factory, school, or other location. Inother embodiments, one or more (or all) plurality of devices 605-615 canbe remotely located from one another.

Each of the plurality of devices 605-615 can gather and report itsoperational metrics to the management server 620 over the network 625,as will be discussed in greater detail below.

Exemplary networks, such as network 625 may include any one or more of,for instance, a local intranet, a PAN (Personal Area Network), a LAN(Local Area Network), a WAN (Wide Area Network), a MAN (MetropolitanArea Network), a virtual private network (VPN), a storage area network(SAN), a frame relay connection, an Advanced Intelligent Network (AIN)connection, a synchronous optical network (SONET) connection, a digitalT1, T3, E1 or E3 line, Digital Data Service (DDS) connection, DSL(Digital Subscriber Line) connection, an Ethernet connection, an ISDN(Integrated Services Digital Network) line, a dial-up port such as aV.90, V.34 or V.34bis analog modem connection, a cable modem, an ATM(Asynchronous Transfer Mode) connection, or an FDDI (Fiber DistributedData Interface) or CDDI (Copper Distributed Data Interface) connection.Furthermore, communications may also include links to any of a varietyof wireless networks, including 4GLTE (Long Term Evolution), 3GPP (3GRadio Access Network), WAP (Wireless Application Protocol), GPRS(General Packet Radio Service), GSM (Global System for MobileCommunication), CDMA (Code Division Multiple Access) or TDMA (TimeDivision Multiple Access), cellular phone networks, GPS (GlobalPositioning System), CDPD (cellular digital packet data), RIM (Researchin Motion, Limited) duplex paging network, Bluetooth radio, or an IEEE802.11-based radio frequency network. The network 620 can furtherinclude or interface with any one or more of an RS-232 serialconnection, an IEEE-1394 (Fire wire) connection, a Fiber Channelconnection, an IrDA (infrared) port, a SCSI (Small Computer SystemsInterface) connection, a USB (Universal Serial Bus) connection or otherwired or wireless, digital or analog interface or connection, mesh orDigi® networking.

The management server 620 is preferably implemented in a cloud-computingenvironment. In general, a cloud-based computing environment is aresource that typically combines the computational power of a largegrouping of processors and/or that combines the storage capacity of alarge grouping of computer memories or storage devices. For example,systems that provide a cloud resource may be utilized exclusively bytheir owners, such as Google™ or Yahoo!™; or such systems may beaccessible to outside users who deploy applications within the computinginfrastructure to obtain the benefit of large computational or storageresources. The cloud may be formed, for example, by a network of webservers, with each web server (or at least a plurality thereof)providing processor and/or storage resources. These servers may manageworkloads provided by multiple users (e.g., cloud resource customers orother users). Typically, each user places workload demands upon thecloud that vary in real-time, sometimes dramatically. The nature andextent of these variations typically depend on the type of businessassociated with the user.

In operation, each of the plurality of devices 605-615 can communicatewith the management server 620, with each of the plurality of devices605-615 acting as a node within the network. The management server 620can track metrics about each of the plurality of devices 605-615 bycommunicating with the PCB on each of the plurality of devices 605-615.

In some embodiments, data obtained by the PCB of each of the pluralityof devices 605-615 is selectively gathered, obtained, monitored, stored,recorded, and/or analyzed by the management system 620.

According to some embodiments, data that is selectively gathered,obtained, monitored, stored, recorded, and/or analyzed, preferablycomprises, for example, working time, current, voltage, power, and soforth from, for example, the vacuum motor, lithium-ion battery,transaxle, brush deck motor, and other components of the floor cleaningmachine assembly. This data or information is preferably received at thePCB 518 (FIG. 14) associated with the lithium-ion battery positioned inthe floor cleaning machine 100. That is, the PCB 518 controls theoperations of each of the components of the device. As described above,the operational data for each of these components can be captured andlogged by the PCB 518 and stored in memory on the PCB 518. In otherembodiments, operational data can be stored in memory on the PCB 518 andtransmitted asynchronously in batches (according to memory size) to themanagement server 620. In some embodiments, the operational data can bestreamed from the PCB 518 to the management server 620 synchronously.

Each device can be managed by assignment of a device ID by themanagement system. The device ID can be an assigned number, a SIM cardnumber, an IMEI, a MAC address, an IP address, or other similar uniqueidentifier. The device ID can be appended to each communicationtransmitted by the PCB 518 to the management server 620.

Stored data or information is preferably analyzed by the managementserver 620 for parameter compliance, and if, necessary such data orinformation is then communicated to, for example, an end user, servicingpersonal, and/or owner. For example, the owner of a floor cleaningmachine assembly can set a threshold of hours of operation for thedevice that are required per week. If the floor cleaning machineassembly is not operated for a period of time that meets or exceeds thisthreshold, the floor cleaning machine assembly is identified by themanagement system 620.

The transfer of data with regard to each individual machine will helpend users better plan for number of machines and employees at eachindividual work site. Companies with sizeable cleaning staff, (e.g.,contact cleaning companies) will find it relevant and useful.

In one embodiment the data or information with regard to usage of eachindividual machine is collected and transmitted daily at a specific timeto, for example, the management server. This will allow end users, aswell as, distributors and dealers to access the information that theyneed, so as to monitor usage of these machines and allow them to extractmaximum efficiency during operations. In another embodiment of thepresent invention, other than information for individual days,cumulative totals and averages are readily available too, and theinformation is preferably updated through the lifespan of the floorcleaning machine assembly. Examples of data or information uploaded on adaily basis include, for example, the number of hours and specific timethe machine was in operation during the previous 24 hours, the monthlytotal hours for machine usage, and the total hours of machine usage.Furthermore, the present invention enables recording and analysis of anaccumulation total for working parts like batteries, vacuum motors,transaxles and brush motors. Since each component has a lifespan, itwill help distributors, dealers, and owners selectively monitor theexact time when these components (e.g., vacuum motor, brush motor andbatteries) need to be changed instead of waiting for them to break down,which will affect the working efficiency of the end users. Anotherimportant advantage of having this data or information transfer is thatin the event the machine breaks down, (e.g., the vacuum motor, brushmotor, etcetera stops working), what has broken down will be selectivelytransmitted to the appropriate servicing personnel by email and/or cellphone text messaging that is/are responsible for the repairs andmaintenance of the machines, management of the end user, and so forth.

FIG. 16 is a flowchart of an example method of the present technology.The method includes obtaining 702 operational data for a floor cleaningmachine assembly, the operational data being generated for any of abattery, a vacuum motor, a transaxle, and a brush motor of the floorcleaning machine assembly.

As mentioned above, this operational data can be gathered by a PCB (suchas PCB 518 of FIG. 5) during operation of the floor cleaning machineassembly.

The method also comprises communicatively coupling 704 a floor cleaningmachine assembly with a management server. As mentioned above, thiscould comprise a wireless communication module of the PCB 518 couplingwith the management server over a network connection.

Once the floor cleaning machine assembly and the management server arecommunicatively coupled with one another, the method can furthercomprise the management server querying 706 the floor cleaning machineassembly for operational data for any of the battery, vacuum motor,transaxle, and brush motor. For example, the management server canrequest battery related operational data from the floor cleaning machineassembly. As mentioned above, this operational data can be stored on thefloor cleaning machine assembly in memory of the PCB. In anotherexample, the management server can request operational data for thevacuum and brush motors.

In another embodiment, the PCB can upload all operational data gatheredsince a last communication session with the management server. Thisoperational data can include operational data for each of the battery,vacuum motor, transaxle, and brush motor.

In some embodiments, the management server is performing 708 at leastone operational data analysis process on the obtained operational data.

Examples of operational data analysis include in one example, comparingthe operational time frames for the floor cleaning machine assembly toan expected operational time frame. For example, the owner of a buildingwill determine an operational time frame that the floor cleaning machineassembly should be utilized for. This operational time frame can becalculated from an expected time based on building square footage, orany other quantifiable metric that can be used to set an operationaltime frame threshold. Once this threshold is established, the managementserver can compare the actual operational time frame utilized over agiven period of time to the operational time frame threshold. If theactual time does not meet or exceed the operational time framethreshold, the management server can alert the owner.

Thus, in some embodiments, the method includes transmitting 710 an alertmessage to an owner of the floor cleaning machine assembly if theoperational analysis indicates that a threshold violating event hasoccurred. To be sure, a threshold violating event is any event in whichoperational data for one or more components of the floor cleaningmachine assembly do not appropriately compare with an operationalthreshold.

In another example, an operational threshold could include a minimumcharging time frame for the floor cleaning machine assembly. If thefloor cleaning machine assembly is not charged for an appropriate amountof time, the battery operation of the floor cleaning machine assemblycan be compromised.

In another example, an operational threshold can be set for the brushmotor, which can include a comparison with another operational metricsuch as total operational time. Assume that the total operational time(e.g., power on to power off) for the floor cleaning machine assembly isone hour, but the brush motor is only operational for fifteen minutes ofthe one hour, it can be deduced that the floor cleaning machine assemblywas not in actual use for the entire hour.

Additional metrics can be gathered by tracking revolutions of thetransaxle, which can be extrapolated into square foot coverage of thefloor cleaning machine assembly. Ideally, transaxle revolutions shouldbe compared to overall operational time to ensure that the floorcleaning machine assembly is moving during power on periods. If thefloor cleaning machine assembly is left on when no work is beingaccomplished, this can lead to unnecessary battery usage.

Knowledge of the approximate square footage of a cleaning area can alsobe used to determine if the floor cleaning machine assembly is beingutilized properly. For example, if by counting transaxle revolutionsthat the floor cleaning machine assembly has only cleaned approximately400 square feet, when the total expected square footage for the cleaningarea is 2,000 square feet, the management server can detect thisdiscrepancy and transmit an alert message to the owner or anotherinterested party.

FIG. 17 is another flowchart of an example method of the presenttechnology. The method includes a step of detecting 802 a failure of acomponent of a floor cleaning machine assembly during operation of thedetecting 802 a failure of a component of a floor cleaning machineassembly during operation or startup of the floor cleaning machineassembly. For example, the PCB can maintain a set of operationalthresholds for each component of the floor cleaning machine assemblysuch as the battery, vacuum motor, transaxle, and brush motor. Wheneverany of these components is operating below this expected operationalthreshold, the failure can be established.

Upon detection of a failure, the method includes the PCB establishing804 communication with a management server, as well as a step oftransmitting 806 a fault message to the management server. The faultmessage can include an indication as to the component that failed, suchas a battery, vacuum motor, transaxle, and brush motor.

If the failure involves a component of the floor cleaning machineassembly that could cause the floor cleaning machine assembly to be asafety hazard, the method can include the floor cleaning machineassembly receiving 808 an emergency shut down signal from the managementserver. The method also includes performing 810 an emergency shut downupon receiving the emergency shut down signal from the managementserver. Examples of emergency shut down procedures are described ingreater detail supra.

In one embodiment, the method includes an optional step of automaticallyordering 812 a replacement part for identified failed component. Thefloor cleaning machine assembly can communicate directly with a thirdparty system over the network to order the replacement part. In anotherembodiment, the management server can identify the failed component andperform a lookup of the manufacturer of the failed component and forwardthe request to the third party system or a local inventory system. Themanagement server can order the part automatically as the fault messageis received. In another example, a replacement component in inventorycan be identified and identified in a repair ticket that is transmittedto a repair technician.

In some embodiments, the present invention enables upgrades to thesoftware that end users are using that may address, for example,compatibility issues, or other necessary upgrades. In one embodiment,the management server can push updates to the floor cleaning machineassembly during operational data transfer operations, or upon poweringup the floor cleaning machine assembly. For example, each time the floorcleaning machine assembly is powered on, the PCB can link with themanagement server and query the management server for updates. This canall occur transparently to the end user, unless a short pause inoperation of the floor cleaning machine assembly is required toimplement the update or for safety reasons.
